Some tips for better search results...

Precede each search term with a "+", as follows:

+Modbus +TCP

Otherwise, any post with either term will match.

Use double quotes around phrases, as follows:

+"Allen Bradley" +ethernet

Otherwise, posts containing these words in separate locations will match.

To exclude a word, precede it with a "-", as follows:

+Modbus -Plus

This will return only posts containing "Modbus" but NOT containing
"Plus".

Note that common words (and, that, etc.) and words shorter than 2 characters
are automatically excluded from searches.
